MACHINE FOR WINDING THREAD. I

STEGIFIGATION forming part of Letters Patent No. 527,602, dated October16, 1894. Application filed December 16, 1892- Serlal No. 456,332. (Nomodel.)

T0 at whom it may concern.-

Be it known that I, JOHN W. FOSTER, of Westfield, county of Hampden,State of Massachusetts, have invented an Improvement in Machines forWinding Yarn or Thread, of which the following description, inconnection with the accompanying drawings, is a specification, likeletters on the drawings representing like parts.

This invention has for its object to provide for quickly adjusting thetension on the yarn going to the spool or other yarn-receiver beingrotated by contact with a winding drum.

In accordance with'this invention, the rail or bar, over which the yarnis drawn on its way to the point where it is to be wound, is

' so mounted as to be readily turned in the are of a circle and thusexpose more or less of the surface of the rail or bar to be acted uponby the yarns.

Figure 1, in vertical section shows a sufiicient portion of a drumwinding frame to enable my invention to be understood; and Fig. 2, aView of Fig. 1, looking from the right.

In the drawings, A represents part of the frame-work, it having suitablebearing stands A for the shaft A having the drum A on which rest thespools, tubes, or spindles on which are to be wound in masses a, theyarn 1 coming from any suitable supply, said spools, tubes, or spindlesbeing mounted in lever-like arms a, bifurcated or made yokeshape attheir front or bearing ends to receive and support said spools, tubes,or spindles, as shown.

The parts so far described are and may be all as usual in drum windingmachines.

The frame A has at its front side suitable stands B on which areadjustably mounted the supports 17, b said supports being held in placeby bolts 19' extended through slots 2 and through a rail 1) providedwith a series of guides b The supports 1), b, have pivotally mountedupon them, preferably by suitablebolts a, a series of carriers. Of thesesupports, the one marked 17, (it being supposed that there are two suchsupports for each tension-bar m,) has carriers g, which are recessed atone side to receive the ends of tension bar m, that'form of carrierbeing considered desirable.

The tension-bar m is supported between its ends by means of one or morecarriers h mounted on the supports b the carriers h being slightlychangedin shape from the carriers g, inasmuch as the carriers h fit thebottom of the tension-bar rather than its ends. The tension-bar m hasits top surface rounded, and it will be covered preferably with somesuitable friction surface.

By loosening the nuts in the bolts c,'the bar may be adjusted into anydesired position, and be left in such position, either as shown in fulllines, or as in dotted lines, it being remembered that the more nearlyhorizontal the top of the tension bar, the greater the friction andtension, and vice versa.

The tension bar will be adjusted from time 7 to time according to thework being done and the tension required on the yarns being spooled.

Having described my invention, What I claim, and desire to secure byLetters Patent,

A tension device for drum winding frames, the same consisting of a railor bar having a rounded friction surface, supports, bar-carrying. armsand adjusting'devices to adjustably pivot or connect the saidbar-carrying arms with the supports 19, whereby, by adj usting the arms,the surface of the bar may be put and held in position to-enable the barto exert more or less friction and tension on the threads being wound,substantially as described.

In. testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN W. FOSTER.
